2021年1月20日 This new process, flotation, whose basic principles were not understood in the early days, was given to metallurgists and mill men to operate. Their previous experience gave them little guidance for overcoming the serious difficulties which they encountered. Few of them knew organic chemistry.

Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.

2021年7月26日 Attachment of particles and droplets to bubbles—the latter being of various fine sizes and created by different techniques (as described in detail)—forms the basis of flotation, a process which indeed was originated from mineral processing. Nevertheless, chemistry often plays a significant role in this area, in order for separation to be effective, as stressed.
